CONGE NTRATING-TABLE Specification of Letters'Patent.

Patented Oct. 6, 1908.

To all whom it may concern: 1

Be it known that We, ALBERT M..KEMI, MERTON W. LOOMIS, and JOSEPH E. Frrz- WATER, citizens of the United States of America, residing at Denver, the city and county of Denver and vState of Colorado, have invented certainnew. and useful Improvements in Concentrating-Tables, and Particularly in the Actuating Mechanism for Concentrators; and we do declare the following to be a clear and accurate description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same;

The accompanying drawings and the mark-' ings thereon form a part of these specifications.

Our invention relates to improvements in actuating mechanism. for concentrators and it consists ofthe details and combinations illustrated the workings thereof.

simple and efiicient mechanism which shall have in addition to the parts usually found in ore concentrating tables, certain parts which give to the machine the reciprocating motion generally used in ore concentrating tables and in addition thereto, certain side motions at each end ofthe table. These side motions may be in the same directionat each end of the table or they may be in opposite directions'at opposite ends or a side motion in either direction may beused'at one end of the table and a reciprocating longitudinal motion at the other end. These side motions are reciprocating and may be increased or diminished in extent .andintensity as pre ferred. By the use of these motions through thismechanism the deck is caused to oscillate with a distinct stroke toward the top or feed side with a slow indistinct return stroke, or with a distinct stroke toward the bottom or discharge end of'the deck, thus causing a The object of our invention is to provide an ore separating or concentrating table with This mechanism may be used upon any concentrating table with any form of deck. The powerimay be applied to the table in any manner desired.

. In the drawings, Figure (1) is a plan view of the deck supporting frame and our improved apparatus upon which the deck is placed. Fig. (2) is a side elevation of the table or concentrator complete, portions being shown in longitudinal section. Fig. (3) is a detail plan of the power or tail end of the table. or concentrator as seen in Fig. (1) on an enlarged scale and showing the different 1 positions of the mechanism of this machine, when in operation or when moved. Fig. (4

1s a perspective of the pivoted slides of (l) and (3).

Similar references indicate corresponding parts in each figure.

Referring to the drawings by letter, a, s, designates the deck or top of the concentrator, e, the floor of the deck which rests upon and is supported by cross-bars .2 under each end of the deck. This cross bar rests Figs.

at each corner of the deck upon an iron blockf.

a is a stay and support for frame of deck, connecting the cross bars 2.

c is the longitudinal side of the frame connecting the cross bars a.

d is a bracket attached to the frame members 0. This bracket is joined by a connecting rod, 6, to an eccentric on pulley d, yivhilch may be used to give the motion to the b is a stay or support for bracket d.

f isan iron block upon which rests the cross bar eand frame members 0', and is the support of this part of the frame which supports the deck. The cross bar 2 is pivotally connected to f at i. The reciprocating movements of the deck are by this pivot guided to move in the direction of the move 'ment of blocks f, and the frame and deck are thus prevented from sliding down in the direction ofits movement. The blocks f work in guides z',which are held in place by being bolted to steel plate 9. Steel plate 9, is pivoted on steel plate f, and is free to move on said pivot; Steel platef is stationary and is bolted to wooden block :1], which is, in turn bolted to frame 0. Frame 0 rests upon frame 0.

h is a crossbar which laterally connects steel plates 9 at each end of the frame, and moves the two steel plates simultaneously. Lever 7c is fastened to cross bar It, at h, and to the frame 0, at is, and is held in position by a set screw 9, on arc Z.

A is the position of the lever 70, cross bar It, and iron block f, when in motion parallel with deck.

Dotted lines B, show the position of lever is, cross bar h, and iron blocks 7, when lever on power or tail end of table is moved to right or towards the lower or discharge side of the table.

Dotted lines C, show the position of lever is, cross bar h, and iron blocks 7', when the lever on same end, is moved to left or towards the upper or receiving side of the table.

By moving lever in, from position A, to position B, cross bar it, is moved in opposite direction, from the handle of the lever. Cross bar It, moves steel plate g, guides i and blocks f, so that blocks f may be moved to any angle desired from that at position A, to that at position B, or any angle to that of forty five degrees from position A.

Blocks f, in position B, move in guides 2' in a direction oblique to line of movement in posit-ion A. In position O, blocks f move at an angle oblique to line of movement in position A, and up to an angle of ninety degrees from position B. This movement of blocks f carries deck a, s in the same direction that the blocks f move. lVhen blocks are in position A, the deck is given a longitudinal horizontal movement. \Vhen blocks f are in position B, the deck is given a side movement towards the lower or discharge side of the table. hen in position C, it is given a side movement towards the upper or receivin side of the table.

vVhen the table is operated in position A, the deck is given a longitudinal motion and the minerals and gangue matter are moved towards the power end of the table or the tail end of the deck. hen the machine is operated in position B, the minerals and gangue matter are given an accentuated motion towards the discharge or lower side. By this movement the gangue matter, silica or other substance, is speedily separated from the mineral values and passed over the table to the discharge side, while the mineral values are moved on towards the end of the deck. The motion when operated from position B, accelerates the separation of the gangue matter from the mineral values over the motion which it has when operated from position A.

When the table is operated from position C, the heavier matters, especially the minerals, are given an accentuated motion towards the upper or receiving side of the deck, and the lighter particles, or gangue matter, driven to the lower side of the deck.

By moving lever 7- from position A, or B, to position C, cross bar h, steelplates g, guides z, and blocks f, are so moved that blocks f move in a direction at right angles to the direction in which they move at position B;

Blocks f, moving in position A, move the deck lengthwise with the table and give it a horizontal longitudinal motion. Blocks f, moving in position B, or in any position from position A, to position B, give the deck a side motion which is increased as the position of the blocks f reaches position B. Blocks f, moving in position C, or in any position from position A, to position C, give the deck an opposite motion from that which it has when moving in position B, or when approaching this position from position A. The movement from positions B, and C, are united with the longitudinal motion of the deck; thus the deck is given a longitudinal and side motion at the same time.

By the use of these improvements the deck is given nine distinct con'ibinations of motions as follows: 1. Each end of deck with blocks f moving in position A. 2. Each end of deck with blocks f moving in position B. 3. Each end of deck with blocks f moiing in position C. 4. Blocks f at head end in position A, and at tail end in position 13. 5. Blocks f at head end in position A, and at tail end in position C. (3. Blocksfat head end in position B, and at tail end in position A. 7. Blocks f at head end in position C, and at tail end in position A. 8. Blocks f at head end in position B, and at tail end in position C. 9. Blocks f at head end in position C, and at tail end in position B. The intensity of the motion in these positions and the length of the stroke are diminished as the lever Z: and the position of the blocks f are changed from positions A, B, or C, towards either of the other positions.

The frame C may be tilted as desired by eccentrics lVflV, mounted near opposite ends of a rod n, journaled near one side of the frame 0 the eccentrics being held in any desired position by a ratchet 'v, and a pawl (not shown), as will be readily understood from Fig. 2.

The position most favorable for the concentration of the particular kind of ore under treatment is readily ascertained by actual experiment. The simple and efi'ective means of adjustment helein furnished provides a table which will more eifectually concentrate almost any kind of ore, or separate the difierent ore values, than other types of machines.

The capacity of a concentrator using our mechanism is equal to and often greatly in excess of that of other kinds of machines.

Slight changes may be resorted to in the several parts described and in theirarrangement without departing from the intent and scope of our invention. We therefore do not Wish to limit ourselves to the exact construction set forth herein.
